Python Logger 对象不可调用

Question

我正在尝试编写一个模块以在不同的脚本中使用它

import logging
from logging.handlers import RotatingFileHandler


_logger_name = "Nagios"
_print_format = "%(asctime)s - %(levelname)s - %(message)s"
_level = logging.DEBUG

class Log():


    def __init__(self,log_file,logger_name=_logger_name,level=_level):
        self.log_file = log_file
        self.logger_name = logger_name
        self.level = level

    def getLog(self):

        """
        Return the logging object

        """
       _logger = logging.getLogger(self.logger_name)
       _logger.setLevel(self.level)
       _logger.addHandler(self._rotateLog())

       return _logger

    def _rotateLog(self):

       """
       Rotating the log files if it exceed the size
       """
       rh = RotatingFileHandler(self.log_file,
                             maxBytes=20*1024*1024, backupCount=2)
       formatter = logging.Formatter(_print_format)
       rh.setFormatter(formatter)
       return rh

log = Log("kdfnknf").getLog()
log("hello")

我看到以下错误:

Traceback (most recent call last):
File "nagiosLog.py", line 45, in <module>
  log("hello")
TypeError: 'Logger' object is not callable

知道为什么我会收到此错误，

当使用 pdb 进行调试时，我确实看到它返回了对象并打印了 dir(log)，但我没有在其中看到 Logger 模块。

我是不是漏了什么

Answer 1

log("你好")

这是错误的。正确的是

log.info("Hello")

日志必须打印日志记录级别，即信息/错误/警告
